In-some areas in which goiter is endemic there is a high prevalence of mental deficiency without any other stigma of cretinism (1-6). When surveying the populations of Tocachi and La Esperanza in highland Ecuador in which goiter is endemic we were impressed by the high prevalence of mental deficiency in the general population; This generalized mental(More)
The aim of this study was to determine the free amino acid pool in plasma and milk in marginally nourished lactating women. Twenty-eight rural women (age, 23.9+/-5y; weight 50.2+/-4.9 kg; height, 148.2+/-4.8 cm) were studied under metabolic balance conditions. Subjects were divided into 6 groups (5-6 women in each), representing rural mothers postweaning(More)
OBJECTIVE To determine the free amino acid pool in plasma and milk in Mexican rural lactating women. METHODS Twenty-eight women with an age 24 +/- 5.0 (+/- SD) years, weight 50 +/- 4.9 kg and height 148 +/- 4.8 cm were studied under metabolic balance conditions. Subjects were divided into five groups (three groups of lactation at 1st, 3rd and 6th month,(More)
Longitudinal studies are the only ones capable of responding to the question of whether cognitive deficits present in schizophrenia follow a stable course and establishing its evolutive relationship with other clinical symptoms of the disease. This article reviews a total of 30 studies published in patients with a first psychotic episode or chronic or(More)
Drawing on the speech acts theory, a linguistic pattern was identified that could be expected to be associated to therapeutic change, characterized by being uttered in the first person singular and present indicative, and by being self-referential in its propositional content. The frequency of the pattern was examined among verbalizations defined as change(More)
Metabolizable energy (ME) and apparent nitrogen, fat and energy bioavailability from the habitual diet were measured in a group of lactating women from a Mexican rural community. Food intake was estimated in 40 women, age 24 +/- 3 y 3-5 m postpartum, body weight 48.7 +/- 5.4 kg and height 148 +/- 5 cm. Habitual diet was predominantly from vegetable sources(More)
Few experimental data regarding protein requirements of lactating women are available. This study was designed to determine the protein requirement of seven healthy lactating women from a poor Mexican community who were 2-6 mo postpartum and had a mean body mass index of 21.8 +/- 2 kg/m2. Nitrogen balances were performed at intakes of 0.8, 1.0, and 1.2 g.kg(More)
Key microbiological conversion processes do not result from the work of a single bacterial species but are performed by a wide variety of bacteria. Up till now, this microbial diversity is usually not tracked during reactor operation and mostly neglected in mathematical models. Nevertheless, experimental evidence is available that different process(More)
